Working with decimal representations of binary wildcard mask bits can be tedious. For the most common uses of wildcard masking, you can use abbreviations. These abbreviations reduce the amount of typing you need to do when configuring address test conditions. For example, say you want to specify that any destination address will be permitted in an ACL test. To indicate any IP address, you would enter 0.0.0.0; then, to indicate that the ACL should ignore (that is, allow without checking) any value, the corresponding wildcard mask bits for this address would be all ones (that is, 255.255.255.255). You can use the abbreviation any to communicate this same test condition to Cisco IOS ACL software. Instead of typing 0.0.0.0 255.255.255.255, you can use the word any by itself as the keyword. For example, instead of using this: Router(config)# access-list 1 permit 0.0.0.0 255.255.255.255 you can use this: Router(config)# access-list 1 permit any
